    Understanding Antidepressants – Or Not

    I was talking with a colleague the other day who’s done a lot of work on central nervous system disease over the years, and it reminded me of something that I said years ago on this blog (and was the first time I was quoted in the Wall Street Journal). Was that an opinion about… Read More

    Kratom and the FDA

    The FDA has made an announcement about kratom, a plant preparation (Mitragyna speciosa) that (depending on who you ask) is a drug of abuse or a way for people to get off of other drugs of abuse. Specifically, it’s used as a way to mitigate opioid withdrawal symptoms, which is reason enough to wonder if it… Read More

    CRISPR and Axovant: What the Market Thinks

    Let’s go to the NASDAQ for some insight on a couple of recent biopharma stories. First off is Axovant, a company that’s interesting in a number of distressing ways. I last wrote about them here, after their Alzheimer’s candidate came up short in the clinic, which was a development that surprised no one who had… Read More

    Expensive Shams Are the Way to Go, Apparently

    Prepare to be weirded out a bit. We’re going to talk about the placebo effect again – actually, we’re going to talk about its evil twin, the nocebo effect. In the same way that a placebo is an inactive/nonexistent agent that people think is doing them good, a nocebo is one that people believe is… Read More

    Microbiome Connections to Disease Get Stronger

    A fair amount of what you read about the human microbiome is hype. There’s no way around it. It’s quite difficult to study this area in a meaningful, reproducible way, and even the best work in the area can only go so far, as things stand now. When differences in (say) gut flora are actually… Read More

    Repurposing Zika

    Oncology drives you to some pretty strange ideas about therapy. But that’s understandable – in what other field are you trying aggressively to kill off parts of the patient’s own body? That’s why chemotherapy started off with the study of people who had been exposed to mustard gas (during the Bari bombing raid), where it… Read More

    A New Piece of the Parkinson’s Puzzle

    Here’s some more news on the Parkinson’s front, with a possible risk factor (and possible protective agent) both coming from an unexpected direction. It’s been known for quite a while now that the alpha-synuclein protein is deeply involved in the pathology of the disease – precipitated masses of it are found apparently killi… Read More

    Those Compounds Aren’t What You Think They Are

    There’s a lot of work in the literature on the TrkB receptor, which responds to brain-derived neutrotrophic factor (BDNF). That name certainly makes the ligand protein sound like a pretty big deal, and so it is: BDNF is involved in a lot of neural development pathways, injuries to nerve tissue, and the like, and given… Read More

    Ultrasound For Brain Drug Delivery – Not So Fast

    I wrote a couple of years ago here about the idea of making the blood-brain barrier more permeable by the use of focused ultrasound, in the presence of injected microbubbles. This would be a very useful thing if it works – as anyone who’s been concerned with central nervous system drugs (or drug delivery in… Read More

    A New Parkinson’s Therapy – Possibly

    There’s a new report of progress in Parkinson’s disease, and from an unexpected direction. Well, it was unexpected for me, anyway. Parkinson’s is, famously, a condition that is driven by the steady deterioration of dopamine-rich neurons in the brain, most particularly in the substantia nigra region. An impressive amount of researc… Read More
